Hi:

I have this problem with the audio of my computer.
When i start pd-extended the audio seems to be only working for pd. If I am playing music from my harddrive or from youtube it just stop until I close pd.

I use Elementary OS Luna (based in ubuntu 12.04) and install pd from the official repositories(http://puredata.info/docs/faq/debian)

I've alredy googled the issue but i could find anything.

Anyone? I would appreciate the help.

Hi there

My problem: when i try to load a patch with the command "pd-extended -nogui -open /home/pi/test.pd" the console send me a message saying "ALSA input error (snd_pcm_open): Device or resource busy" and "ALSA output error (snd_pcm_open): Device or resource busy"

But, when I use the command "pd-extended -open /home/pi/test.pd"(without -nogui) everything works fine.

Note: the error "ALSA input error (snd_pcm_open): Device or resource busy" and "ALSA output error (snd_pcm_open): Device or resource busy" also occurs when I choose the default audio card of the Raspberry PI but not when I choose a generic USB audio card all this with GUI of course.

System: Raspberry PI with 2013-12-20-wheezy-raspbian

I appreciate any ideas. Thanks.

Hi im reading miller's book, and i want to know the answers of the exercise to compare with my results. if someone was kind enough to respond I would be grateful.

Exercises
1. A sinusoid (Page 1) has initial phase φ = 0 and angular frequency ω =
π/10. What is its period in samples? What is the phase at sample number
n = 10?
2. Two sinusoids have periods of 20 and 30 samples, respectively. What is
the period of the sum of the two?
3. If 0 dB corresponds to an amplitude of 1, how many dB corresponds to
amplitudes of 1.5, 2, 3, and 5?
4. Two uncorrelated signals of RMS amplitude 3 and 4 are added; what’s
the RMS amplitude of the sum?
5. How many uncorrelated signals, all of equal amplitude, would you have to
add to get a signal that is 9 dB greater in amplitude?
6. What is the angular frequency of middle C at 44100 samples per second?
7. Two sinusoids play at middle C (MIDI 60) and the neighboring C sharp
(MIDI 61). What is the difference, in Hertz, between their frequencies?
8. How many cents is the interval between the seventh and the eighth har-
monic of a periodic signal?
9. If an audio signal x[n], n = 0, ..., N − 1 has peak amplitude 1, what is the
minimum possible RMS amplitude? What is the maximum possible?

hi there,

Im doing an external in C and i wonder if there is a method or a way to send messages from the external(inside of the object) that is received by an receive object

sorry for the english, and thanks

Anyone???

Nevermind. The problem is solve. The message ";pd dsp 1" needs a |delay 2000|.

This is what i looking for, I appreciate. Can i find the code of all objects in pd's source code??

Cmon... anyone??
how does it work the send and receive objects??

Congratulations!!! it is just great and funny!!
